<h3 class="section">C.5 <samp>configure</samp> Options</h3>

<p>Here is a summary of the <samp>configure</samp> options and arguments that
are most often useful for building <small>GDB</small>.  <samp>configure</samp> also has
several other options not listed here.  See <a href="../configure/What-Configure-Does.html#What-Configure-Does">(configure.info)What Configure
Does</a>, for a full explanation of <samp>configure</samp>.
</p>
<div class="smallexample">
<pre class="smallexample">configure <span class="roman">[</span>--help<span class="roman">]</span>
          <span class="roman">[</span>--prefix=<var>dir</var><span class="roman">]</span>

</pre></div>

<p>You may introduce options with a single &lsquo;<samp>-</samp>&rsquo; rather than
&lsquo;<samp>--</samp>&rsquo; if you prefer; but you may abbreviate option names if you use
&lsquo;<samp>--</samp>&rsquo;.
</p>
<dl compact="compact">
<dt><code>--help</code></dt>
<dd><p>Display a quick summary of how to invoke <samp>configure</samp>.

<dd><p><strong>Warning: using this option requires <small>GNU</small> <code>make</code>, or another
<code>make</code> that implements the <code>VPATH</code> feature.</strong><br>
Use this option to make configurations in directories separate from the
<small>GDB</small> source directories.  Among other things, you can use this to
build (or maintain) several configurations simultaneously, in separate
directories.  <samp>configure</samp> writes configuration-specific files in
the current directory, but arranges for them to use the source in the
directory <var>dirname</var>.  <samp>configure</samp> creates directories under
the working directory in parallel to the source directories below
<var>dirname</var>.
</p>
</dd>
<dt><code>--norecursion</code></dt>
<dd><p>Configure only the directory level where <samp>configure</samp> is executed; do not
propagate configuration to subdirectories.
</p>
</dd>
<dt><code>--target=<var>target</var></code></dt>
<dd><p>Configure <small>GDB</small> for cross-debugging programs running on the specified
<var>target</var>.  Without this option, <small>GDB</small> is configured to debug
programs that run on the same machine (<var>host</var>) as <small>GDB</small> itself.
</p>
<p>There is no convenient way to generate a list of all available targets.

<p>There are many other options available as well, but they are generally
needed for special purposes only.
